<h1>A11Y Nav</h1>
<p>Library for accessible navigations. Currently a work in progress, but it has bare minimum functionality needed for production use. Will be adding features as I need them.</p>
<p>
The site navigation utilizes keyboard functionality using the arrow keys,
enter, escape, and spacebar commands. Arrow keys can navigate between
previous/next items and also move down into a nested menu. Enter will open
a nested menu and escape will close the current menu. Spacebar will open
the current menu.
</p>
<p>Currently works in all modern browsers except IE 11 until I figure out how to correctly polyfill the UMD build.</p>
<h2>Example Usage</h2>
<pre><code class="language-js">
const a11yNav = new A11YNav(document.querySelector(".a11y-nav"), options);
</code></pre>
<script type="text/plain" class="language-html">
<ul class="a11y-nav">
<li>
<button aria-expanded="false" aria-controls="id_here">First Level Item</button>
<ul id="id_here">
<li>
<button aria-expanded="false" aria-controls="id_here_2">Second Level Item</button>
<ul id="id_here_2">...</ul>
</li>
</ul>
</li>
<li><a href="#">Simple Link</a></li>
<li>

<img src="image.jpg" alt="" />
</div>
